摘要:
The disclosed principles provide a roofing product and related methods of manufacturing having antimicrobial properties. The antimicrobial properties are provided by an antimicrobial delivery system including antimicrobial materials compounded, e.g., mixed together and melted, with polymeric materials. The antimicrobial delivery system is applied to roof covering material during the production process. The roof covering material may be sheets, shingles, panels, or roll stock.

摘要:
A method for thermally revitalizing a damaged polymer-containing material, consisting essentially of applying heat from an external heat source to the surface of the object to temporarily raise the surface temperature of the object above the softening point of the polymer is disclosed. A device for performing thermal revitalization on a polymer-containing material is also disclosed.
